The Spacer (OEM Part No. 3128237617) is a structural replacement part compatible with the SIMBA H1254 underground drilling rig. Manufactured from heat-treated alloy steel, it is designed for use within the drill feed system, serving at the shaft or assembly spacing position. This component maintains precise axial alignment and controlled spacing between rotating or sliding elements, contributing to stable feed movement and mechanical integrity. Its robust construction ensures resistance to deformation and operational stress under demanding underground drilling conditions.
